I got same error messages in registry.log file just after deplying to CVS with the Spec value is "30 * * * *" and the statuses of the service of CVS were "Expired" and "Inactive" in DevTest 10.2.

I changed the Spec value to "30 * * ? * *" or "* 30 * ? * *", then still I got same error messages in the registry.log but the statuses of service of CVS became "Completed" and "Active" and the test case ran periodically.Results in detail:Spec "30 * * ? * *": the test ran every HH:MM:30 .Spec "* 30 * ? * *": the test ran every HH:30:00 .
